T 0 all whom it may concern:

Be it known that we, GEORGE PUTMAN JONES, gentleman, and WILLIAM ANDREWRINDEEss, ins ector, both of the city of Moncton, in t ie county ofI/Vestrnoreland, Province of New Brunswick, Canada, have inve/ntedcertain new and useful Imfprove- Our invention relates to improvementsin spike pullers, and the objects of our invention are to provide aneXceedin ly sim le and efficient form of device for pul ing spifrjesfrom railroad ties and such as will grip the spikes with absolutecertainty and may be readily adjusted to position thereover; and itconsists essentially of the improved construction hereinafter describedin detail in the accompanying specifications and draw ings andspecifically set forth in the claims.

In the drawings, Figure l is a perspective view Of our improved spikepuller. Fig. 2 is a vertical section of the same.

In the drawings like letters of reference indicate corresponding arts inboth figures.

Referring to the rawings, A represents the frame which comprises twoparallel and vertically extending members a and b, con nected byhorizontal rods c. The bottom of each of the side members a and b has anopen slot d cut therein into which the head of the rail is adapted tofit, whereby two legs e and f are provided which rest on the base of therail.

B represents a vertically reciprocating claw bar having projections g,7i, i and j thereon which enter into vertically extending slots 7C, l, mand n provided in the side members a and l). The claw bar isreciprocated by suitable means, that shown comprising a rack o formed onthe rear side thereof which engages a partially formed pinion wheel Cwhich is rotatably supported on a shaft p journaled in the side membersand has an operating handle q connected thereto, whereby it may beoscillated.

r and s represent the gripping jaws which are centrally lowerextremities formed with co-acting claws u and o. Their upper extremitiesare conivoted at t and have their nected with a projection fw on theclaw bar by means of suitable links :c and y. For convenience in liftingthe spike puller, a bail D is pivotally connected to the upper endthereof, the bail illustrated being U-shaped in form and having inturnedends extending into holes in the sidev members of the frame.

In operation, the spike puller is adjusted in position with regard tothe spike and the claw-bar lowered until the claws on the grippingjawsare on opposite sides of the spike. The claw bar is then raisedthrough the operation Of the handle q which closes the gripping aws andcauses the claws thereon to get a firm hold of the spike, which isthereby raised.

While the device has been described herein with great particularity ofdetail, yet it will be readily understood that in carrying out theconstruction of the same, changes .within the scope of the appendedclaims might be made without departing from the spirit of the invention.

What we claim as our invention is A spike-puller, comprising a framecomposed of two, similar, thin side-plates, each said plate taperingtowards its top and having one edge formed with a waving contour, eachsaid plate being cut away at itslbottom to straddle a railroad-rail, andeach said plate having verticallyextending slots near the edge thereofOpposite the edge with the waving contour, and rods connecting the saidplates g a vertical claw-carrying rack bar disposed between the twoplates and of greatly less width than that of the space between the twoplates, said rack-bar having, lon one face thereof, a rack and, at itsends, horizontal cross-pieces engaging said vertical slots; a pinion forengaging the rack and operatively mounted on one of said connecting rodsand a handle for actuating the pinion.

Signed at Moncton, Province of New Brunswick, this first day of October,1907.
